Question

If a sound wave in the air has a frequency of 256 hertz and is traveling at a speed of 331 meters/second. What is its wavelength?

Answer 1

The wavelength is 1.29 m.

The frequency `f` and wavelength `λ` are related to one another and to the speed of the wave `v` by the formula

`fλ = v`, so

`λ = v/f` = `(331"m·s⁻¹")/(256"s⁻¹")` = 1.29 m
